I’m thinking this 10.5 Pro might need a battery replacement soon.

Maybe yours needs a new battery too in that case :)
Such sharp drop happens to me easily when I run a game in the foreground with 30% brightness or so. If I watch YouTube video all day with such sharp drop, I’d check battery health and pay some attention to it.
